Justification:
The blackish skate is endemic to the Ecuador, Peru and Chile in the Southeast Pacific. It is a deepwater species recorded from the continental slopes at depths of 590 to 1,000 m. Reaches a maximum size of 45.7 cm total length (TL). Nothing known of its biology. Generally no fisheries in its deepwater habitat at present, but likely to be taken as bycatch if deepwater trawl fisheries develop and expand in this region.

A deepwater skate species recorded on the continental slopes, at 800 m depth off Algarrobo, Chile (33°20'S) by de Buen (1960), at depths of 780 to 960 m by McEachran and Miyake (1984), and 590 to 1,000 m depth off Chile (Lamilla, unpubl. data). Individuals examined off Chile were 13.7 to 45.7 cm TL (males, n = 28) and 5.4 to 12.0 cm TL (juvenile females, n = 27). Adult females possibly occur in deeper water. Nothing known of its biology.
